ADHESIVE-APPLYING MECHANISM FOR WRAPPING. MACHINES Original application filed November 1,

1918, Serial No. 260,629, new Patent No. 1,554,369, dated-September 22, 1925.- Divided and this application filed September 14, 1925. Serial No. 5 6,259,

This invention relates to machines for, wrapping articles such. as bread loaves, or the like, in an envelope preferably of wax paper, so as to sealed against infection and also to prolong the period of preservation. v Specifically, the present application is a division from my co-pending application, Serial #260,629, filed the first day of November, 1918, and renewed the 16th day of January, Patent No. 1,554,869., dated September 22, 1925; while the main object thereof is the provision of novel mechanism functional to apply adhesive to wrapping sheets at the regions corresponding to the subsequent folds into envelope. formation.

Other objects and attendant advantages will be obvious from the following description of a typical embodiment of my invention, as illustrated by the accompanying drawings; while the appended claims serve to succinctly define its character and scope.

In the accompanying drawings Fig. I is a part plan view'of a wrapping machine at thefregion where my novel adhesive applying me hanism is conveniently embodied. Y 2

Fig. IIis a longitudinal section through that portion of the preceding figure indicated by the arrows II-II thereon; and,

Fig. IIIis a'plan view of a portion of the paper sheet from which successive wrap-, pers are severed and showing, diagrammatically, convenient locations of applied adhesive.

While the form of my invention illustrated and described herein'is believed, at this time, to be a preferred embodiment thereof; it is obvious that the same is susceptible of change and variation; accordingly the right is hereby reserved to effect such modifications as'may be deemed desirable to meet different requirements.

In the following detailed explanation of my invention like reference numerals are appliedto corresponding parts in all the views.

Proceeding now to a description of the embodiment of my invention illustrated the be substantiallyhermetically 1924; which matured into upon a shaft numerals 4, .5 designate, fragmentary side portions of a wrapping machine framework, such as forms the subject-matter of the hereinbefore referred to patent, said side portions being united by .girts 6v in. the well known manner.; v7 indicates the main lineshaft by which motion is transmittedto various mechanisms incorporated in the machine,

and it is provided with a power pulley 8 under control of a friction clutch 9, movable by an appropriate connection 10, fitted with; a hand lever 11 and an auxiliary slide rod 12 arranged for movement from the other end of the wrapping machine. A rock-shaft 13, oscillated by, an arm 14:, is connected by an interposed link 15- to a" crank pin 16 carried by a spur wheel couple 17., on a shaft 18, which is driven by means of a worm gear 19 from the line shaft 7 The paper feeding and severing mecha nism is driven by the shaft 18, just referred to, which shaft carries the main feed roller 20. This roller 20 co-operates with a companion roller 21, in drawing paper P, from a suitable source of supply, and'advancing the sameto the printing and adhesive applying mechanism, now to be described. The main feed roller 20 aforesaid, also serves as a platen for. a printing'device by which daubs of adhesive dFig. III-are applied to the paper 1?, at the proper intervals, consistent with the location of the folds in the final package. This printing device includes a series of padded arms of which those' indicated at 22, 22 have single printing faces; whilst those marked 23, 23 have multiple faces, that the adhesive printing is effected asshown in Fig. III. These padded arms 22, 23am adjustably set 24, which is constantly driven by a gear wheel 25, from the gear on the roller shaft 18. In rotating,fthe paddedfaces of the arms 22, 23 dip into a trough 26, in which an ample amount of adhesive is constantly maintained. The trough 2600mmunicates through a duct 27, with a cup 28,, adapted to receive the inverted supply container 29. In the present instance, I .prefer to use melted parafiin asthe adhesive, and

, in circuit with a convenient source of electric current b way of conducting wires 31 connected to t '18 terminals 32.

The upper feed roll 21, is fixed upon a shaft 33, journaled in slide blocks 34, vertically guided in yokes 35'; While springs 36,

operative upon said slide blocks press the roll 21, into contact with the roll 20 and a positive driving connection is effected through the upper gear of the hereinbefore mentionedspur wheel couple 17. The surface of the upper roll 2lqis interrupted, as shown, in order to clear the adhesive prints 03 upon the traversing paper web P. The rolls 20, 21 are further functional as severing: devices in cutting the web of paper P into units of the proper size. The severing is accomplished by a knife 37, which is carried by the roll 20, and co-operative with a groove 38, in the upper roll 21. As shown, the knife 371 is received and guided within a longitudinal groove 39-, so as to be capableof movement in aradial direction under the influence of springs 40, and it is actuated by means of cams 41- having cooperative annuli42, and associated segmental plates 43, in accordance with my hereinbefore referred to patent. Preferably the paper web P is not completely severed by the knife37, but to maintain its continuity is left intact at points eta-Fig. III aswill be readily appreciatedwithout further explanation; and, as it leaves the rolls 20, 21, it is guided through channels 45, assisted by intermediate supporting strips 46, to nip rolls 47 fixed upon a shaft48 journaledin bearings 49 supported by leaf springs 50.

As hereinbefore stated, paraffin is employed as an adhesive medium. and the imprints d initially applied to the wrapping paper -P may become'set before the package has been fully formed. In order to insure the proper sealing, I provide the machine at suitable intervals with heating devicesnot sh0wn-preferably electrically heated, by means of which the imprints d aforesaid are'sufliciently fusedto bring about aperfect union of the folded wrapper. Such heating devices arelocated at points, where best adapted to ensure good results as explained in the referred to patent.

From the foregoing it is thought that the operation of this invention will be clearly understood without further. detailed description; while it is equally obvious minor detail changes may be effected without departing from the scope thereof, or the sacrifice of any of its advantages.

Having thus described my invention, I claim: 3

1. In a wrapping machine including a supply of adhesive with means for maintaining such adhesive in a molten condition during application, the combination of the material feeding and severing platen roller and serial means including single and multiple-faces co-operative with the platen feed roller in applying said adhesive to wrapping sheet material at regions corresponding to the subsequent folds thereof and prior to partially severing such material.
